PURPOSE:To prepare a polysaccharide having a main structural component consisting of glucose, mannose, galactose, and glucuronic acid, forming gel at normal temperature, by cultivating Bacillus polymyxa-8. CONSTITUTION:Novel mold of Bacillus polymyxa S-8(FERM P-7035) is cultivated in a medium using starch, glucose, sucrose, etc. as a carbon source, urea, meat extract, pepton, etc. as a nitrogen source, containing an inorganic nutritive source, at 5-9pH, at 10-40 deg.C for about several days. Consequently, a polysaccharide having a main structural component consisting of glucose, mannose, galactose, and glucuronic acid in a molar ratio of the constitution of 5:4:3:3, forming gel at normal temperature, is obtained. |
